Cover Unlocking and Positioning Mechanism for Wire Drawout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric wire drawout part structures require a jig for unlocking the cover, making it difficult to detach and align the cover and pipe body, leading to complex operations and potential position gaps.
Innovation Solution
An electric wire drawout part structure with an integrated unlocking and positioning part on the cover, located near locking portions, featuring pipe body engaging parts, tape winding capabilities, and a pressing mechanism to facilitate easy unlocking and positioning of the pipe body without a jig.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a jig is used for unlocking the cover and positioning the pipe body, then the cover can be unlocked and the pipe body can be positioned, but the operation becomes complex and the jig must be safe-kept
Solution Approach 1:
The patent combines the unlocking function and positioning function into a single integrated structure called the 'unlocking and positioning part' on the cover. This eliminates the need for a separate jig, as the cover itself contains both the locking arm for unlocking and the pipe body engaging part for positioning, thereby simplifying the operation while maintaining reliability
Solution Approach 2:
The cover is designed with multi-functionality by incorporating both unlocking and positioning capabilities into a single component. The unlocking and positioning part serves dual purposes: it unlocks the cover from the housing through the locking arm mechanism and simultaneously positions the pipe body through the pipe body engaging part, eliminating the need for dedicated unlocking tools
2Object-affected harmful factors
If the pipe body is not positioned, then the electric wires are protected, but a gap occurs in wiring
Solution Approach 1:
The cover's unlocking and positioning part performs self-positioning of the pipe body during the unlocking operation. When the cover is unlocked, the pipe body engaging part automatically engages with the pipe body to position it correctly, eliminating the need for separate positioning operations and ensuring proper wiring alignment while maintaining wire protection
3Reliability
If the cover is locked to the housing, then the electric wires are protected, but the cover cannot be detached for maintenance
Solution Approach 1:
The locking mechanism is designed to be dynamic rather than permanent. The locking arm can transition between locked and unlocked states, allowing the cover to be securely attached during normal operation for wire protection, yet easily detached when maintenance is needed by simply operating the unlocking and positioning part
